Convert only WMA lossless -> Flac

[RSONNAD]

I have recently purchased a SONOS system. This supports WMA, except for WMA lossless.

So I now need to go through my library and convert only the lossless files (5000 out of 20000 total) to FLAC.

I see with db Batch Converter you can filter on extension, but I need to filter on specific codec.

Does anyone have suggestions for how to do this, or any other ideas on how to make a library SONOS friendly, without manually going though every file. I think one other option would be filtering on size. Most of the WMA Lossless are over 15k meg in size, so maybe I could trigger of that instead of the codec. But I still see now way to do that.

I'm not sure how well this would work, but you could try just doing a search in windows Explorer by size, highlighting the files shown, and right-click --> Convert To should work.

Could you use the extra columns that dMC (Reference) adds to Windows Explorer to search for the files?

Yes, it looks like you can sort wma files that way. The column name is "Audio Quality" and it reports my lossless wma files as "Perfect (Lossless)".

Unfortunately, this no longer works on Windows 11, where search seems to have been dumbed down.

You can use Batch Converter, it can list based on Type and Lossless, add the column 'Quality'

I used Batch Converter. I didn't see a Quality field in Filter or as a column in the list.

My solution was to use the bulk converter and, after filtering on wma file type:
- click the "List" button
- wait for the list to fill completely (took a couple minutes, due to 5K files on OneDrive)
- right-click and "unselect all"
- sort on bit rate
- select the low bitrate files
- click the checkbox on one of the files. The list disappears, but when it's reopened, the high bitrate files are checkmarked.
- click Convert

But I now see that I could have added the extended property Audio Quality to the columns and used the same steps. The "invert selected" right-click option didn't seem to work, and took a couple minutes each time (due to 5K files and OneDrive) so I gave up on that and used the sequence above, which worked.

I've been using dMC and associated programs for about 20 years now and am a big fan. Thanks for this inexpensive, extremely feature-packed, convenient, and useful suite of tools!
